my god I was there. It is hell.
um. I don't know what to tell you. I suffered though that, started hearing voices, losing my mind. But slowly I came out of that hollow emptiness that is a sharp sting and a dull ache at the same time.
Well slowly it changed for me. I started dealing with other symptoms, like anxiety, paranoia, panic attacks. Personally I'd rather deal with those than what I had before with the emptiness. I am getting along with my voices now and life is going well.
So... the morel of the story is: I got nothing.
I was there, it was hell, and I came out. I'm doing well now. I don't know how it changed though. I forgave myself for being too weak and forgave myself for being so pitiful and started letting myself hope for more. And then it came. But it took a long long time.
Hang in there, keep searching for answers. Or maybe change will just come to you, but it might just be a different set of problems.
